Admissions advisors are responsible for providing information and encouragement to future students. As a part of the college or university staff, their job is to organize recruitment events to inform students and their families on everything they need to know about admission processes, application requirements, financial aid possibilities, and enrolment.
To get a job as an admissions advisor, you will need a bachelor's degree in marketing, sales, or a related field. You might consider yourself working for the institution where you were studying. In this case, taking on student jobs while you are enrolled, like working as a resident assistant or campus tour guide, would really boost your chances of getting hired.
Essentially, your job will be to promote the university or college you work for, so communications skills will be your most important asset. Building a relationship with prospective students will be essential, so if you prefer working in the solitude of your office, this might not be the position for you.
